Abstract：The sample was decomposed with nitric acid-hydrofluoric acid-hydrochloric acid. After removing silicon and fluorine by perchloric acid smoking, the salts were finally dissolved with hydrochloric acid. Al 396.152 nm, Ca 315.887 nm, Ba 233.527 nm, Mn 257.610 nm and Zr 339.197 nm were selected as analytical lines to determine aluminum, calcium, barium, manganese and zirconium in silicon-manganese-zirconium inoculant by inductively coupled plasma atomic emission spectrometry (ICP-AES). The influence of matrix effect and spectral interference on determination caused by coexisting ion irons was reduced and avoided via sample solution dilution. The mass concentration of aluminum, calcium, barium, manganese and zirconium in range of 0.50-4.00 μg/mL was linear to its corresponding emission intensity. The linear correlation coefficients of calibration curves were higher than 0.999 9. The detection limit of aluminum, calcium, barium, manganese and zirconium was between 0.60 μg/g and 1.1 μg/g. The relative standard deviations (RSD, n=10) of determination results for aluminum, calcium, barium, manganese and zirconium in silicon-manganese-zirconium inoculant according to experimental method were between 1.6% and 3.0%. The results were consistent with those obtained by other methods.
